Results of limbal transplant in case 2 (primary diagnosis: aniridia). (A) The external appearance of the right eye showing an extensive fibrovascular membrane covering the cornea. The picture was taken during surgery while a peritomy was being done. (B) Slit lamp photograph (fluorescein stained) of the same eye 3 days after surgery. Corneal epithelial cells have started to migrate from the transplanted limbus and are migrating across the host cornea. The quadrant indicated with arrows, where no epithelial cell migration is seen, corresponds to the site where a spacer, fashioned from corneal collagen (without epithelial cover), was placed. (C) Slit lamp photograph (fluorescein stained) of the same eye, 5 days after surgery. Three quarters of the host surface is re-epithelialised. The quadrant corresponding to the spacer (arrows) has remained bare. (D) Slit lamp photograph (fluorescein stained) of the same eye, 7 days after surgery. The remaining quadrant is almost covered by cells migrating from the other quadrants. (E) Slit lamp photograph (fluorescein stained) of the same eye taken on day 8 post surgery. Re-epithelialisation of the host corneal surface from donor limbus is complete. (F) Slit lamp photograph of the same eye 6 weeks after surgery. The cornea is clear and the surface is smooth as illustrated by the broad slit beam. Remnants of the lens capsule (following needling for congenital cataract) with a central opening are now clearly visible.
